Just a bit of fun. The five Platonic solids, each spinning on its own axis and at its own rate. The visual equivalent of a fidget spinner.
The shapes come from Python classes I wrote to have something to experiment on with quaternions. (The rotations are done with quaternions, also from a Python class.)
The Python objects generate files POV-Ray, which did the rendering, can read and use to build geometry.
Simple tools, simple result, but it gives me something fun to do in my retirement.
